Here’s how you can get a string with table keys with comma delimiter in Lua: function getKeys(name) s = ' for k, v in pairs(Gname) do ' s = s.k.' ,' end ' return s end There’s G table in Lua which lets you to get a table or variable by its name, so calling Gname gets us a table we want to get keys from. To read values from slice, use slice.unpack, it use a format string to control how to read into a slice as below table (same format character are also used in buffer.pack). Notice that you can use pb.typefmt to convert between format and protobuf type names (returned from pb.field ).

Greetings, fellow Lua enthusiasts; you’ve finally stumbled across another post to peruse! Recently for ‘work purposes’, I decided to investigate reading external files into tables in an attempt to create an NFL game picker. Unfortunately I don’t have that code at hand, but I’ve written another little program, which reads an external file into a table line-by-line, before checking it for duplicate entries. Before we get started, I’ll just point out that, after I’d done this, I discovered a much simpler way that I’ll mention afterwards. Samsung j7 prime frp bypass with combination file. But this seems to work fine, even though it might be less efficient that the ‘proper’ way. Before you start, though, you’ll need to make sure you’ve created a file called ‘names.txt,’ and that it’s in the same directory as the lua file you’ll create below. It’ll also help if you’ve filled the file with at least a few lines of text (like a name per line, perhaps). Anyway, code below*:

io.input('names.txt') -- External file to read from names = {} -- Create table

Lua uses tables to represent packages as well. When we write io.read, we mean 'the read entry from the io package'. For Lua, that means 'index the table io using the string 'read' as the key'. Tables in Lua are neither values nor variables; they are objects.

--FUNCTION 1 --READING FROM FILE INTO TABLE

function readFromFile(names) local counter = 1 --How many times have we looped through this function? repeat temp = io.read('*line') --Every time you call io.read(), you read the next line of your io.input() file if temp ~= ' then --While there's something read in names[counter] = temp --write the line into the current line of the table counter = counter + 1 --add 1 to the counter end until temp nul --Until nothing is read in end

--FUNCTION 2 --CHECKING FOR DUPLICATES

function checkForDuplicates(names)

local repeated = false --So we can tell if anything's been repeated for i=1, #names do --Have we found a duplicate field = names[i] --The current value we're comparing other values to for j = i + 1, #names do test = names[j] --The 'other values' mentioned above if test field then --If the two values are hte same How to bypass frp on samsung phones lock. Samsung j210f frp mrt. print(test. ' is repeated') repeated = true end end end

if repeated false then print('No names repeated') --If nothing's repeated, let the user know end end

readFromFile(names) --Call the function passing the table 'names' to it checkForDuplicates(names) --..and check for duplicates in the same table

Some problems I came up against:

Every time you call io.read() it reads a new line, so you have to ‘use’ each call you make! Also, remember you can use the function in different ways:

io.read() and io.read(“*lines”) perform the same function; they read in whatever you’ve chosen line-by-line. I find it easier to add the “*lines” bit, even though it’s not entirely necessary, as it makes the code that little bit more clear.
io.read(“*all”) reads in the whole file at one
io.read(“*number”) reads in a number (I’m not entirely sure how this works; I haven’t tried it out yet), and
io.read(num) reads in a string of upto num length (again, I haven’t tried it myself, but it seems fairly self explanatory).

Not using repeat. The first time I tried it, I tried to use a while look. Obviously this leads to a situation where you’ve finsihed reading in your last line, but, because the line wasn’t empty, you run through the loop again, reading in an empty line. Another one of those obvious answers that makes you feel like an idiot when you realise what you’ve done!
Realising there’s a better way!

Yup, as I mentioned above, there’s a better way of doing this. Rather than writing out your own function, you can use Lua’s built in IO fuction. io.lines(), and one of the build in functions to add to the table:

io.input('names.txt') --Set our input file local nameTable = {} -- Create our table
for line in io.lines() do --Use the for loop and io.lines() to traverse the file table.insert(nameTable, line) -- Lua function to add to a table end --..and we're done!

We’ve managed to condense ‘function1’ from the initial code down to, essentially two lines (the for loop and the table.insert line are doing all the work). So, how does it work?

io.lines reads through our external file, a bit line io.read() (I’m sure there is a difference, but I’m not sure what it is!). We then assign the value of the line we just read to a variable in the for loop (in this case, we’ve called it ‘line’)
The fuction table.insert() takes two arguments in this case:

Argument 1 is the name of the table
Arguement 2 is the name of the variable you want to insert into the table

And that’s it! If it doesn’t do anything else, it illustrates that it’s always worth checking if your language has a built in function that’ll do your work for you! The first function has been significantly simplified, and I’ve learned a new Lua method. Success!

*Apologies for the lack of colour in the code; I had enough trouble as it was getting the font changed and the line spacing correct! If anyone knows of a better way to put code (complete with correct formatting) into a wordpress blog, I’ll be forever in your debt!

How To Read A Table Name In C Lua 2

** the # actually returns the number of values until a non-initialised entry (ie, nil) is reached. So while it is often the number of entries in a table, if you’ve got any ‘gaps’ in your table, it’ll usually only return the number of values up until the first gap. For example:

tableWithGap = { [1] = 'a', [100] = 'b', [1000] = 'd', [2000] = 'f'} print (#tableWithGap)

…prints out “1” rather that the “4” that you might expect, because there are ga
